Abstract
An apparatus for transporting and for conveying fabrics, individual articles and other material, in particular for feeding web-shaped material into a machine which processes it, for example a paper web into a printing machine, with at least one conveyor element formed for engagement with the material, a guide rail, in and/or along which the conveyor element(s) can move, and a drive device comprising the conveyor element in order to convey the material into and/or through the machine via the conveyor element, wherein the drive device is formed by an electric linear motor whose secondary part or rotor device comprises and/or bears the conveyor element(s) and whose primary part or stator device is mounted in a stationary manner on the guide rail, and the guide rail is formed from a non-magnetic and non-conducting or electrically insulating material, preferably a plastics material, and comprises therein one or more electrical conductor strands to which the stator device is coupled and/or connected so as to be energized.
